UA-135H • Part No. 4025470 • Serial No.________________________________
Dehumidification
The highly efficient Ultra-Aire 135H dehumidifier utilizes refrigeration
to cool the incoming air stream below its dew point. This cooled and
drier air is used to pre-cool the incoming air stream resulting in a
significant increase in overall efficiency. After the pre-cooling stage,
the processed air is reheated by passing through the condenser coil.
The heat removed by the evaporator coil is returned to the air stream,
resulting in an overall temperature increase of the air leaving the unit.
The Ultra-Aire 135H is controlled by 24 volt remote wired controls. A
variety of controls are available suitable to various applications.

Fresh Air Ventilation
Optional fresh outdoor air may be ducted to the unit via a six inch
round duct. This provides fresh air to dilute pollutants and maintain
high oxygen content in the air. The amount of fresh air ventilation can
be regulated by a variety of dampers and controls.
Air Filtration
The Ultra-Aire 135H includes air filtration to improve indoor air quality.
A MERV-11 media filter is standard. An optional MERV-14 deep
pleated 95% media filter is available for optimum air filtration and to
reduce potentially harmful airborne particles. If the optional filter is
chosen, the standard filter operates as a prefilter.
